Chern characters for curved dg-algebras
Kuerak Chung, Bumsig Kim, Taejung Kim
We construct a quasi-inverse of the cochain map on the negative cyclic complexes of the second kind induced from the quasi-Yoneda embedding on a curved dg algebra. This gives an ex…
A chain-level HKR-type map and a Chern character formula
Kuerak Chung, Bumsig Kim, Taejung Kim
We construct a Hochschild-Kostant-Rosenberg-type quasi-isomorphism for the negative cyclic homology of the category of global matrix factorizations on a smooth separated scheme of…
Nullity of the Levi-form and the associated subvarieties for pseudo-convex CR structures of hypersurface type
Kuerak Chung, Chong-Kyu Han
Let , , be a smooth manifold with a pseudo-convex integrable CR structure of hypersurface type. We consider a sequence of CR invariant subsets $ M=\mathcal S_0 \s…
Categories as models on a suitable algebraic theory
Kuerak Chung, Giovanni Marelli
We explain how categories, and groupoids, can be seen as models for a Lawvere -theory, where is the category of graphs, and show that for Lawvere $…
Yet another delooping machine
Bernard Badzioch, Kuerak Chung, Alexander A. Voronov
We suggest a new delooping machine, which is based on recognizing an n-fold loop space by a collection of operations acting on it, like the traditional delooping machines of Stashe…
